The late arrival of spring has everyone ready to hit the fields running when fields finally dry out. Some will be tempted to forgo applying herbicides prior to planting to ensure fields get planted in case another wet period arrives. This is an exceptionally risky proposition for no-till fields because it provides weeds a head start on the crop and a competitive advantage for the rest of the season. If everything falls in place perfectly, this practice can be successful. But any delay in getting back into the field to apply the burndown and residual herbicides can have a big impact on the success of weed control and, therefore, profits.
